HENRY IOTTIN, OF PARIS, FRANCE.

CASH REGISTER AND RECORDER.

SPECIFICATION forming part of Letters Patent No. 575,372, dated January 19, 1897.

Application filedIelJruary 4, 1896. Serial No. 578,003. No mocleLl Patented in France May 31, 1893, No. 230,494.

To all, whom it may concern:

Be it known that I, HENRY POTTIN, a citizen of the Republic of France, residing at Paris, France, have invented certain new and useful Improvements in Cash-Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to increase the efliciency of cash registers and recorders.

The said invention consists in the construction and combination of the various parts of the same, as hereinafter more particularly set forth and claimed. 7

The said invention has been patented in France by Letters Patent dated May 31, 1893, No. 230,494.

In the accon'lpanying drawings, Figure 1 represents an external plan view of the machine. Fig. 2 represents an elevation of the same on the customers side, the outer casing being removed. Figs. 3 and 4 represent two vertical sections at opposite ends of the mechanism, taken just inside the casing. Fig. 5 represents a view similar to Fig. 1, but with the outer casing horizontallycut away. Figs. (5, 7, and 8 represent elevations, taken from three different sides, of the recording and stamping mechanism detached, Fig. U also showing the casing in vertical section. Figs. 9 to 30 represent detail views of the various parts of the mechanism; and Fig. 31 represents an auxiliary safety device applied to and combined with the 1nanipulating-lever, the operative parts being shown in side elevation and the casin g in vertical section.

In the said drawings, a designates the main casing of the machine, which forms, as usual, a desk on the side toward the cashier. It is provided with guide-slots b, Fig. 1, for the ordinary sliding pusher-buttons d, to which rack-bars c are attached, these last being arranged under the inclined part of the casing, Figs. 2 and 4:. The said rack-bars gear, respectively, with the teeth e of disks f, arranged in corresponding series. These disks are independent of each other and loosely mounted on a common shaft A, Figs. 2, 3, 4, 23, and 2-1. Each disk f has a graduated indicating-segment f attached to it. These segments are arranged so that the numerals O to 0 thereon will be visible through windows Z) in the inclined part of the casing. The cashier on receiving a sum of money slides down the pusher-buttons in their slots and stops each when the right figure appears at the window to indicate the sum received. As illustrated, the mechanism can register receipts up to nine hundred and ninety-nine francs and ninety five cent-imes, French money, and the totalizer can add them up to nineteen thousand, nine hundred and ninetynine francs and ninety-five centimes. On the said shaft A are also mounted a series of loose indicating-segments f each of which is connected to one of the said disks by a'bar f, the first disk on the left being thus connected to the first segment on the right, the second disk on the left to the second segment on the right, and so on. \Vhere the bars f must pass through intervening disks, the latter are provided with arc-shaped slots f which allow the motion of said disks and bars independently about the said shaft without obstructive contact, Figs. 5, 10, 20, 23, and 24C. The short bar f connecting the innermost diskf and segment f of course does notpass through any disk.

The above system of connections insures the exhibition by segments f through the windows I) in the customers side of the cas ing, of the same numerals that simultaneously appear, as aforesaid, through the windows 1) on the cashiers side. A third series of segments f Figs. 3, 19, and 20, respectively, integral or rigid with segments f bearin each instance, like the other two series, peripheral numerals from 0 to 9,but these are embossed so as to be available for stamping and recording. In each instance the same stun will be recorded by segments f which will be eX hibited simultaneously to the customer and cashier through the said two sets of windows.

Each of the disks f has three series of gearteeth 6, (already described,) c, and a The teeth c operate the totalizer. The teeth 6 with abutment-pieces, hereinafter described, keep the disks from turning while stamping goes on. They also prevent the cashier from changing the sum shown before operatingthe totalizer.

All the mechanism is driven by a springdrum G, the arbor of which is provided with a stud-plate g, arranged to be engaged by a pivoted pawl y when a lever-arm rocks in one direction and by a pivoted pawl g", also on the end of the said arm, when the latter rocks in the other direction. in either case the arbor is turned in the same direction, that which applies tension to the said spring, by reason of the arrangement of the said pawls and ot' the studs on the said plate. The said arm belongs to a three-armed lever G l igs. at, t), and 10, and thisis mounted with and moves with an operating-lever Therefore, whether the latter moves up or down, each motion of it winds the spring. A detent g prevents the said arbor from turning back.

The spring-drum ti carries a crown-wheel G,whieh always, by intervening connections, tends to drive the main shaft 1 on which nine cams, hereinafter described, are mounted; but such rotation takes place only at the proper time and to the required extent by reason of the special construction and arrangement of the connecting devices. At one end of the shaft ll and on the same side of the machine as the lever g a cam 13 is mounted, having lateral studs formed thereon, with which a locking double lever B under pressure of spring ll, normally engages. The lever G has arms beside the arm already described. One ofthcse two acts on the upper end of locking-lever 1-3 when the operating-lever 7 moves upward, and the other one of the said arms does the same when the operating-lever moves downward, in either case removing lever 13 from contact with one ot the studs of the said stud-plate and allow ing the said spring-drum to turn until the said lever 13 presents its upper end under the other stud of this plate. As the two studs of. 2

the said plate 13 a re placed at right angles to each other the rotary motion is through onefourth of a circle when the handle is moved in one direction and through three-fourths of a circle in the 01 her. \Vhen the driving-shaft l; is thus caused to turn one-fourth of a revolution, a cam ll on the said shaft acts on an antii'riction-roller it, carried by a pivoted frame 71 to block the disk 1''. The said frame is provided with a spring or springs 71 for l tolding the said roller against the said cam; also with flat sprii'igs 7a, the free outer ends of which bear upward against the studs 71. 011 angular arms If, so as to hold the locking rollers 71 on the upper ends of the said arms, Figs. 27 and 2a, with a resilient pressure in the spaces between the teeth (J and against the said teeth. \l'hen the said cam is not in position to act on the roller it with. this looking effect, the rollers 7i fall out of such engagement with the said teeth and free the disks f. The frame It and arms 71 are mount. ed, as shown, on a shaft 72, parallel to shaft 13, but obliquely above the same.

The period of three-fourths of a rotation of the driving-shaft during which the rollers 71/ are freed from looking engagement with the rotation and a quarter rotation.

and of the rubber-faced roller teeth a, as aforesaid, is advantageously divided into two periods, respectively, of a hall'- .Duringthe former of these periods the rollers 71. are not between the teeth it, but very lightly in com tact with them. During the latter oli these periods the said rollers are held in between the teeth, not with such force as to lock the disks against rotation, but so as to be in position ifor instantly effective locking aclion when forced farther in at the end of the first indicating operation which exhibits the amount of the individual payment through windows 1: and To this end the cam ll. is provided with three peripheral eam-taces 1, 2, and 3 of dil'l'erent radius. \Yhen the roller 78 is in contact with the cani't'ace 'l, which is that of greatest radius and one-fourth ot? a circle in extent, the disks 7' are locked. hen the said roller is in contact with the cam-face 2, which is oi? the least radius and one-half of a circle in extent, the rollers h are entirely out from between the teeth a ol. the said disks, and when. the said roller 71 is in. contact with the cain-ilace 3, oi. intermedi ate radius and a fourth of a circle in extent, the said rollers 71, are held lightly between the teeth a of the said disks, but ride lightly over them as the said disks turn, the springs 7r yielding to allow this action. Simultaneously with this lOOlilllg action another cam l on the said shaft B acts on a roller 1' at the end of one of the arms of a bell-cranlc lever i and thereby moves the shutter 1." on. the other arm of the said lever, so as to uncover the window 7} toward the CtiSlOiutll', Figs. 3 and 21.

The recording and. stamping mechanism, liligs. 2, El, (.3, 7, and 8, comprises two standards j, su 'iporting suitable luiarings for the shat't j, opposite a locked door. The recording mechanism all vibrates on or around this shaft and is removable therewith at will. It is supported and. guided. by two slides, by a cross-bar on the customers side and by studs on. the cashiers side. A jointed handle] bears against these studs, being held down. by springs. by turning up this handle and. pulling it outward the cashier can remove the recording mechanism [from the casing in order to replace the roll of paper. On this shat'i is mounted a frame provided with the bearings of the. spindles ot' the paper-rolls) and The spindle of paper-roll is provided with a but ton j at one end for convenience in withdrawing the said spiiu'lle when a new roll of paper is to be supplied. The said roll, while in use, is free to turn on the said spindle. This is the winding or supply roll. The un winding or storage roll. j may be removed after-lifting the ends of the levers) or spri ngbars which hold. the ends of the shaft in their bearings. One of the ends of the rollj is provided with a ratchet-wheelj actuated by a pawl 7 pivoted on a levery This lever is hinged at one end to the removable t'raine ot on which the stamping is done.

the recording mechanism, and carries at the other end a roller j which is intermittently acted on by cam K of driving-shaft B, this action taking place when the lever g has reached its lowest position. At this moment the stamping is complete, and the roll j" turns far enough to present a fresh part of the paper web j 11 against the rubber face of the bed-roll The said ratchet-wheel is provided with a retainingpawl.

In order to record the sum received, it is only necessary to move the printingrollerj against the embossed segments f the web of paper being between. This is done by means of cam j on the driving-shaft B acting on a roller 14 carried by a support which is adj ustably attached to the frame of the registering mechanism, said frame being mounted on shaft j so as to vibrate thereon. In such vibratory motion the roller presses the paper against the embossed figures on the segments f which print on the paper the sum shown at the windows of the desk or casing, as before described. The frame carrying the said roller 3' and the paper-rolls will be returned toits first position by a replacingspring j 15 when the camj ceases to operate on the rollerj A flat brake-springj bears on the spindle of roller j 3 to prevent too rapid unwinding of the paper. The same embossed figures of the segment-sf may also be stamped on a bill to show payment. The cashier,when beginning to operate the lever, inserts the bill through a slot 7' in the casing, Figs. 3 and 6, and between the guide-webs 17 and the embossed disks These guide-webs then remove the bill from the raised figures which have stamped it.

In the totalizing mechanism there are five pinions Z, having ten teeth each, adapted to gear with the teeth a of the disks f, being, respectively, in the same vertical planes, Figs. 2, 4t, 5, 11, 12, and 13. These pinions and a supplemental pinion Z which has no corresponding disk f, are mounted loosely on a shaft L, parallel with the driving-shaft B. This shaft L turns in bearings, which are rigid with a rock-shaft L, that has also a rigid arm Z carrying at its end a roller Z intermittently acted on by cam O of shaft B when the operating-lever g is moved into proper position. Simultaneously the rock-shaft L oscillates so as to brin the pinions into gear with the disks f, as aforesaid, Fig. 13. As soon as the cam 0 moves away from the roller Z, a replacing-spring Z", acting on another arm of the rock-shaft L, turns the latter back to its former position, removing. the said pinions from the said disks. Each pinion Z is integral with a cam m, Figs. 11 and 1S, and a spring-drum m, the other end of whose spring m is attached to a sleeve carrying a toothed segment m the said drum being also provided with aratchet-wheel m. Each group formed of a pinion Z, cam m, and spring-drum m is independent of the others. All are mounted loosely on shaft L. Each support of shaft L has a double flat spring-pawl m detachably fastened to it, one of the leaves of the said spring being shorter than the other, to operate as hereinafterset forth. The hub of each segment m carries also a disk on, closing the drum on the side opposite to the cam m. An arm projecting from the periphery of said disk carries two fixed studs m m at different distances from the center of the disk, one of the said studs being also more advanced than the other in the direction of rotation. Said disk is also provided with a stud m on the side opposite to that which carries the said spurs. The supplemental pinion Z, which registers thousands, has no cam and only an empty drum m The rock-shaft L, Figs. 11,12, 13, and 17, has flattened faces permitting the fastening thereto of smallbrackets 7t ,Wl1lGll afford bearin gs for a small shaft niprovided with a sleeve or hub 77,, having a series of arms is and an additional arm M, the latter carrying at its end a roller 17;, held in contact by a spring 02 with the cam N, Figs. 12, 13, and 17, on the driving-shaft B. This cam acts on the said roller,when the said shaft is rocked, by lifting the lever g, and thereby turns the arms it into position under the studs m of the disks m respectively, so as to prevent the said disks from turning and keep the springs m compressed, Fig. 13. \Vhen the operating-lever g is brought down to its lowest position, the segments Z have been moved thereby away from the disks f to their position of rest, Figs. 1.1 and 17, and the arms at release the studs aforesaid. This successive order of release is due to the successively-increasing width of the said studs or striking-pieces in the series of disks. The flattened rock-shaft L carries also a second set of devices consisting of bell-crank levers 0, located in the same vertical planes, respectively, as the corresponding cams m, Figs. 11 and 18. Each lever 0 turns on its own pivot-pin 0, fixed to one of the supports of the shaft L, and each pivot-pin is surrounded by a helical spring 0 whereby its lever 0 is forced against the corresponding cam m. Each lever 0 carries a stud 0 arranged for contact, at the proper time, with one of the two spurs m m" aforesaid when their disk m is rotated.

A flat bar 13 is adjustably fastened in front of the pinions Z. Five brackets 13 are fastened on this bar, each forming a pair of supports for the ends of a small spindle, on which, Figs. 11, 12, 13, and l i, a five-toothed wheel 13 and a fifteen-toothed wheel 19 turn side by side. The fifteen teeth of each wheel 19 are divided into five sets of three teeth, each set successively gearing with the segment m correspondin g to the said wheel. Each of the fivetoothed wheels 19 is in the same vertical plane as the corresponding ten-toothed pinion Z. As already stated, the said pinions Z are vibrated collectively in their said vertical planes from one to another extreme positions about shaft L. In. one of these positions the decimes pinion. 1 gears with. the centimes live-toothed wheel 11*, and so on, as far as the supplemental pinion Z" for thousands of francs, which gears with the hundreds-of-franes .li vetoothed wheel. In the other position the said pi nionsZ- gear with the said pinionsf, except that the centimes-pinion j, the lirst of the series, does not gear with anything except its actuating rack-bar.

A cam l on the driving-shaft 1; acts on a roller r", carried by an arm 1) of a small rockshaftp, to hold a series of llat locking-springs f, also carried by the said shaft, against the wheels 9 respectively, to prevent their rotation when the said wheels 1) are not in. gear with the said pinions 7. As soon as these latter are again moved into such engagement the cam 1 ceases to act on the roller p and the springs p, moving away from the wheels 1) leave these latter free to turn. A s1"lrin p at all times bears on the arm 1), holding the roller 21 in position for the action of the said cam.

When the lever g is raised into its highest position, the mechanism above described is ready lior totalizing, the pinions Zbeingin gear with the disks 1'', the arms a under the studs m and one of the spurs m or nz in each pair against the correspondingstud 0 of the lever 0, while the llat springs :2)", s above stated, lock the live-toothed wheels 72 and the ilifteen-toothed wheels 1'). The lever g is now brought down. A cam (g on the shalTt l3, Figs. ll) and 30, rocked thereby, acts onv a roller (1, integral with a toothed segment g, which is loosely mounted on a fixed rod and engages and turns a similar segment if, loose on the shaft A, this latter segment carrying a bar g, parallel to the said shaft, this bar being also partly supported by an arm g" on the said shaft. This bar If is thus brought against the heels of the segments 1 and turns the latter, as well as the segments f and disks], back to ZGl'O, the arms of the segments/' all resting on a stop-bar -u when the movement is complete. Each diskfand the pinion Z meshing therewith have then been turned back as many teeth as the numeral indicates which was presented by said disk in the sum exhibitcd and recorded. The spring-drums in, being rigid with the said pinious, respectively, and their disks on) being locked at that time by the arms a, the above movement winds the said spring-drums. As soon as this return ll'lOVOlllOl'lli to zero is ended the cam 0 moves away from the roller Z, the flat rock-shaftl'i', acted on by its helieoidal spring, removes the pinions Z from the correspmiding disks/and engages them with the live-toothed wheelsp The .llat sp rings p move away from the wheels 1-, leaving them free to rotate. The levers n are released from the studs m of the disks m.

The function of the cams m, respectively integral with the ten-toothed pinions Z, is to free the disks m from the correspondin g stopbeen turned liar enough by the action ol. the appropriate rack-bar on its pinion Z to cause the stop-lever e which is in contact therewith to release the stud n17 ol. the said disk, the latter is thereby freed and will. turn nn der the action of its spring until. (:lIOOliQtl. by the contact of the next stud in with the said lever, or' if the said cam has turned i'ar enough to carry the stud on said lever beyond the lines of travel of both the studs on the said disk the latter will turn. thrliiugh a complete revolutioi'i until. stopped by the contact of its stud an with the lever 12. This complete revolution also occurs whenever the stud m, having been caught as above described, is released by the continued. action of the said cam on the lever o.

In rotating, the segment m'engages one ol. the sets o't three teeth oi the lilYteen.toothed wheel p causing the latter to turn to the extent of three teeth, and. also turning to the extent of one tooth the live'toothed wheel. 1*, integral with wheel. 1'). This latter wheel turns the units-pinion geared therewith, to the extent of one tooth or one unit. 'llhen the ten-toothed unit's-pinion Z has made a complete rotation, indicating ten units, it will turn the adjacent pinion, representing tens, to the extent olf one tooth. This continues throughout the decimal series in. the usual way. ll'hon consulted at. any time, the aforesaid devices will show the total ot' all sums registered since the beginning, the mechanism being started at zero.

To bring the totalizing mechanism back to zero after a series oilf operations-a days work, for example the llgurcs shown on the totalizer are read, but without counting thousands. Then, after linding the number which will. make one thousand when added to the number already registered, the said first number is registereifl, whereby all the SPllilg-tll'tllllS and connected gearing oi.- the mechanism. will be brought to zero except only the thousands barrel or drum,which has no spring and may beturned to zero by hand after raising the operating-lever to diseir gage the pinion Z" :l'rom the corresponding live-toothed wheel f". When the operatinglevcr g is brought down to its lowest position, and the driving-shaft 1.3 begins to retate, the cam l releases the shutter, which falls and closes the window 7/ toward the customer.

A signal-belll/ is rung at the end. of the operation by a cam T on driving-shalt 1', which raises a hammer t and compresses a spring I", the hammer tailing when the rotation oi the said shaft is ended. A wingregulator r is controlled by a toothed wheel it on driving-shalt ll, gearing with a pinion "I", which drives a wheel 2*, and thereby a worm 7' connected to said regulator.

The general. operation oil. the machine is as follows: Assuming that all the parts of the apparatus are at zero, and that, to begin with,

lovers 0. \Vhen any one of the said cams has a sum of :live hundred and twenty-six :lrancs IIO and seventy centimes has to be registered, the cashier moves the buttons (Z in their guide grooves or slots until the figure 5 appears at the hundreds-window Z), the figure 2 at the tens-window, and so on. There is no possibility of the cashier making a mistake, for he can read on the horizontal line of windows Z) the sum named. If the amount is on a bill, the latter is handed over by the customer and inserted in the slot 7' The window b on the customers side is at this time closed by the shutter Z which hides the number 526.70, which have come to the said window. The cashier now raises the lever g. The shaft B, having been set free, revolves one-qu arter of a rotation, durin g which movement the cam H brings into operation the device that locks the toothed disks. The cam J works the mechanism whereby the sum is recorded on the web of paper j and the bill is stamped. The cam I raises the shutter Z and the customer can see whether the cashier has registered the proper sum. The cam G rocks the flattened shaft L, bringing the ten-toothed pinions Zinto engagement with the toothed disks f; but before this movement begins the cam N has brought the levers a under the studs m of the disks m and the cam P rocks the shaft 19 so as to make the springs 17 lock the wheels p The cashier then lowers the operating-lever g to its first position, that of rest. The shaft 13 is freed again and turns three-fourths of a rotation, coming also to a position of rest. During this movement the cam H frees the toothed disks f, and the cam Q brings the segments and the toothed disks Z back to zero, that is, back to their position of rest; but in being thus brought back to zero the said disks turn the ten-toothed pinions Z to the extent of five teeth for the eentimes-pinion, of two teeth for the tens-pinion, and so on, making the spring-drums m show at their upper part the figure 5 for the centimesdrum, the figure 2 for the tens-drum, and so on. The extra drum for thousands has not moved at all, not being in gear with any disk, and still shows zero. As soon as the return to zero has been made the cam 0 moves awayfrom the rock-shaft L, which is brought back to its first position by a spring. During this movement the ten-toothed pinions Z move away from the disks f and come into gear with the fivetoothed wheels 19*. The cam P sets free the five-toothed wheels 1)", and the cam N allows the arms at to be disengaged from the studs m but as none of the springdrums has made a complete rotation the cams m, integral with the said spring-drums, still hold the striking-pieces of the bell-crank levers 0 on one of the spurs m or m of the said disks m locking the latter. Therefore the totalizing mechanism retains the position to which it was brought by the return of the toothed disks f to zero and shows five hundred and twenty-six francs and seventy centimes. The cam I has now set free the shutter, which has the window 11 moved into position to cover The cam K has carried the leaf j forward, so as to be ready to record a new operation, and just at the moment when the driving-shaft B ceases to turn, the cam T sets free the hammer t, which strikes the bell t and announces that a sum has been cashed. During the entire rotation of the driving-shaft B the wheel R, carried by the said shaft, has been turnin g the wing-regulator 0. So the mechanism has returned to rest, the indicator shows zero, the recording devices have printed 526.70 on the paper, and the totalizing devices show the number 526.70. Everything is ready for a new operation.

Assuming that there is now to be shown registered and recorded a second sum of six hundred and seven francs and forty-five centimes everything proceeds as before; excepting the totalizing mechanism. \Vhen the lever 9 reaches its highestposition,the sum of sixhundred and seven francs and forty-five centimes is recorded on the paper web j. hen the said lever g has been lowered, the return to zero of the indicating-disks is made. During this return the centimes-pinion Z turns to the extent of five teeth and its spring-drum to the extent of five units. The tens-pinion Z turns to the extent of four teeth and its drum to the extent of four tens. This latter drum had turned during the first registering operation to the extent of seven tens, and as it is graduated from O to 9 it now presents the figure 1. On the other hand, it has made more than one complete rotation, so the striking-piece 0 has been disengaged from the last spur m of the disk on, which is no longer prevented from turning except by the arm 01, still presented under the studm The unitspinion Z turns to the extent of seven teeth, and its drum m, which consequently turns to the extent of seven units, has come back to the figure 3 having been'already turned to the extent of six units during the preceding operation. As the said drum has made more than one complete revolution its lever 0 has become disconnected from the spurs of the corresponding disk at, which is no longer retained except by the corresponding arm n. The tens-pinion has not turned and its drum still shows the figure 2 of the preceding operation. The hundreds-pinion has turned to the extent of six teeth, and as its drum already showed the figure 5 it has returned to the figure 1. As the revolution has been a complete one the arm 0 has become disconnected from the spurs of the corresponding disk miwhich is no longer retained except by its arm n. The registerortotalizer now shows 12315; but the cam 0 moves awayfrom the flattened rock-shaft L, which is oscillated forward by its spring. The pinions Z move away from the disk f and come into gear with the five-toothed wheels f, already set free by the springs 13. At this moment the cam N sets free the arms a, which are withdrawn by their spring a, settingfree the studs m of the disks inf, when those of the said disks corresponding to units, tens, and hundreds which have already been disconnected from the arms 0 are turned by their spiral springs, but stopped at the end of one rotation by the contact of one of their spurs on each disk with the strikingpieee of the corresponding lever 12. The tens-disk in) in each rotation carries around with it the three-toothed segment or, and the said segment during this motion causes the corresponding fi fteen -toothcd wheel p to turn to the extent of three teeth. The units-pinion Z, in gear with this pinion, is thereby moved forward one teeth, so that its drum shows one unit more, that is to say, the n umcral l instead of In the same way the complete rotation of the unitsdisk m transmits an ad vanec movement to the tens-pinion t to the extent of onetooth, and thus causes the tensdrum to show the figure 3 instead of 2. Lastly, the complete rotation of the hundreds disk 1H5 transmits an advance of one tooth to the extra pinion Z for thousands, and causes the thousan ds-d rum in. to show the :figure 1 instead of 0. As this drum is divided into twenty parts instead of ten parts, itturn s only one-twentieth for each thousand. For that purpose its twenty-toothed pinion gears with a five-toothed wheel 9; but on the hub of this wheelp" is carried a wheelp of ten teeth only, operated by a segment m which has only two teeth instead of three, Figs. 29 and 230. The shutter has now closed and the bell rung, as in the first operation. The mechanism is ready to be operated a third time.

As shown in Fig. 31, I make use also of an auxiliary safety device applied to the operatingl.ever, as follows: During the complete raising of the operati ng-lever the stud-plate turns one-sixth of a rotation, and during the return downward movement of the said lever the said disk turns another sixth of a rotation. If in the said upward movement of the lever the plate f is made to turn only the twelfth of a rotation, that will suffice for the pawl to pass from one pin or stud of the said plate to the next, beca use the pawl ha ving turned also a twelfth of a rotation in the opposite direction from that of the plate will have been displaeeda sixth of a rotation with regard to any point of this plate. Now if we stop here the raising of the lever g the stud 9" will prevent the spring G from turning the stud-plate f, so that we can bring back the lever g to its lowest position. This movement, by the action of pawl will turn the plate another twelfth of a rotation in the same direction as the first twelfth. "Fe may thus indefinitely turnv the stud-plate in the same direction, thereby winding the spring G, with. some risk of breaking it. Similarly when the lever g is in its highest position it is possible to make only a twelfth of aturn downward, then returning to said position, and so on. To guard against the risk of breaking the spring by such movements, I employ mechanism which prevents the ascending levergfrom coming back before arriving at its highest position. The same mechanism acts in the same way during the movement of descent. This safety mechanism comprises a sector 5 attached to the arms and g of the three-armed lever on the shaft of the operating-lever The sector g" bears four notches, of which two, 710: are turned in. one direction, the others, in the reverse direction.

The plate B, keyed on shaft l3, presents two cams 9, one projecting at the fron t of said plate, the other onv its eireumference. The cam g performs the function of a stop for the double lever 12 Fig. i. On a small fixed horizontal shaft g there are mounted loosely two superposed levers, having branches g. The longarms of these lovers present reversely-beveled faces, which tend to bear on the periphery of the sector g" under the influence of spring 9, attached to the she rt arm of each lever. The short arms of these lovers are provided with terminal rollers, one of which is placed. opposite the cam-groeve of the plate 13, the other slightly in advance of that plate. When the operating-leverg is at its lowest position, all is arranged as in Fig. The roller of the upper lever 9 is on its cam g and the roller of the lever r re. on the periphery of the plate 13''. The large arm of g is raised, so that the sector 9* may turn from left to right. \Ve may then raise the operating-lever, but after a twelfth of a rotation the beveled. face of the long arm of. the lever g lodges in the first notch and prcvents the lever from reversing its motion. It therefore is not possible .for the lever g to do so until it has reached the very end of its upward course. On reaching this the lever 5 produces a disengagement, and the cam-plate l5 turns with the shaft .13 one-fourth of a retation. At this time the cam leaves the lever g, and the cam g begins to raise the roller on the end of the short arm of the lever 9". We may then lower the lever g, but a fter a twelfth of a turn the beveled face of the lever engages the notch g and prevents the rising of the lever g, as its descent when rising was previously prevented. Thus .in either case the said lever must be pushed up or down to the end of its course, which will produce always the disengagement desired and prevent the fraetu re ot' the spring.
